Title: Hydraulic transmission for construction vehicle - has emergency brake with motor fluid volume set to minimum on braking
Inventor: ARENZ BRUNO
IPC: B60T1/08
Filed: 1977-09-06
Abstract: The construction vehicle is powered by a hydraulic transmission in which the speed of the vehicle is set by the pressure output from the main pump and the throughput of the hydraulic motors. For higher torque and lower speeds, the throughout volume is at a maximum. Emergency braking is backed-up by a safety servo which sets the throughput of the motors to a minimum. The minimum setting of the motor throughput corresponds to the stationary setting. The vehicle brakes then do not have to operate against the transmission torque.

Title: Digital display for drafting machines - has indexing error correction for display provided by rounding unit and has coded glass disc
IPC: B43L13/08
Filed: 1977-11-23
Abstract: The digital display system consists of the drafting machine head with arm whose spindle carries a coded glass disc impressed with angular information. An opto-electronic transducer converts the angular data to a binary-coded form together with a rotational sense signal. These digital signals are fed to an up-down counter, are decoded to drive a digital display. To compensate for inaccuracies in the indexed positions of the head, a rounding device is provided so that at discrete positions of the linear divider or protractor, the digital display value corresponds to the indexed position. The rounding unit contains an incremental counter to provide a correction pulse, and a start/stop circuit for the counter activated from the indexer on the head.

Patent DE-2807417-A1 (DE)
Title: Plastics composite loading pallet - assembled from elongated, one-piece, components held together by screw or claw connections
IPC: B65D19/00
Filed: 1978-02-22
Abstract: Plastics pallet is composed of several identical parts each of which is an integral, one-piece moulding. The components are relatively elongated and arranged parallel side-by-side, with their respective surface of contact perpendicular to the top of the resulting pallet. They are held together by connectors extending parallel to the top of the pallet. These connectors are suitably screw-threaded tubes and/or screws, or else they may be "claw" connectors. The advantage is that the connectors are not coplanar with the top of the pallet and do not, in consequence, interfere with any load put upon the pallet.

Title: Multicolour photocopier using two=step process - has separate filter for each stage so that complementary colours give accuracy good enough for documents, accounting statements etc.
Inventor: KASAHARA NOBUO
IPC: G03G15/01
Filed: 1978-03-29
Abstract: The multi-colour photocopier has two process steps of complementary colours, and each with a separate exposure, toner transfer and fixing cycle. Each step is processed with a separate filter so that major colours are presented with reasonable accuracy while shades are distinguished from each other. The system allows colour copying of documents, multicolour accounting statements etc. where accurate colour is not required. The first image is processed with the tone of the second colour and vice versa. The system is simple and therefore economical.

Title: Pipe burst safety unit for hydraulic systems - has back pressure valves in passage between control and cylinder connection
Inventor: WESSEL GUENTHER
IPC: F16L55/10
Filed: 1978-08-03
Abstract: The safety unit is located between a hydraulic control unit, and a working cylinder in the feed pipe to a cylinder working chamber. A back pressure valve arrangement is located in the passage through the unit, between the control connection and the cylinder connection. The valve arrangement is raised in the opening direction by a servo pressure, coming via a pipe from a servo-controlled source. The source supplies a servo pressure, when a lowering movement occurs, to the hydraulic control unit, to compare it with a pressure in a hydraulic connection pipe.
Patent DE-2838717-A1 (DE)
Title: Supercharger for IC engine - has converging funnel utilising ram effect of vehicle motion to compress incoming air
Inventor: TEMPLIN ERWIN
IPC: F02B27/00
Filed: 1978-09-06
Abstract: The engine has an air inlet shaped as a converging funnel. The wide open end is placed at the front of the vehicle so that air is forced into it by the forward movement of the vehicle. The narrow outlet goes to the inlet side of the carburettor. The motion of the vehicle drives air through the converging funnel and thus compresses it. The air reaching the carburettor to serve the engine is thereby effectively raised to a higher pressure without the use of a compressor with moving parts. This supercharges the engine with a high degree of efficiency and reduces the fuel consumption.
Patent DE-2841642-A1 (DE)
Title: L-Tryptophan microbial prodn. - by cultivating Escherichia coli mutant under aerobic conditions, sepg. cell mass, suspending mass in buffer and reacting
Inventor: WAGNER FRITZ PROF DR
IPC: C12P13/22
Filed: 1978-09-25
Abstract: The microbial prepn. of L-trytophan comprises (a) cultivating a L-tryptophan, tryptophanase negative mutant of Escherichia coil W 3110 in a nutrient salt soln. contg. assimilable C and N sources, inorganic salts and L-tryptophan, under aerobic conditions at 28-40 degrees C and at a constant pH in the region 6-8, and sepg. the cell mass formed from the suspension, when growth is complete; (b) suspending the damp cell mass obtd. in an inorganic buffer soln. of pH 7.5-8.5, adding indol, L-serine, pyridoxal phosphate and a non-ionic surfactant or a lipophilic adsorbent to the suspension, reacting this at 28-42 degrees C and finally isolating L-tryptophan from the reaction mixt. L-Tryptophan is an essential amino acid which is used as a nutrient and feedstuff additive and is also used for medical purposes. The reaction of indol and L-serine in the presence of the lipophilic adsorbents or non-ionic surfactants gives high yields and improved productivity, while avoiding the disadvantages of previous processes which used expensive C and energy sources and an excess of D, L-serine.

Title: Tubular heat exchanger mfr. - has fins formed by plates which have flanged holes with press fit on tubes
Inventor: ERNST EGON
IPC: F28F1/32
Filed: 1978-11-30
Abstract: The heat exchanger is built from tubes (2) which fit into holes formed in rows in plates (1). The holes are formed with a flange (3) with its edges (5) turned inwards to form a second smaller flange (7). Two diametrically opposite slots are cut in the rounded edge, (5) of the flanges (3, 7) which imparts a degree of resilience to these flanges. The plates are pushed over the tubes and pressed together so that the flange of one plate fits inside the flange of the adjacent plate. This axial pressure causes the inner flange (7) to be compressed onto the tube (2) to provide a sound joint with good thermal conduction.
